This is our go-to spectrum and we HIGHLY recommend this spectrum for most freshwater aquariums. Nothing brings out the vivid colors and enhances your tank like a full, rich RGB (Red,Green,Blue) spectrum of light. It not only makes your fish pop in color, it also won’t promote algae growth.
What is a blue light good for in a fish tank?
Blue LED lighting creates a calming ambiance in your aquarium. Many fish enthusiasts say the blue light serves best as a transition light between light and darkness. So, you can use the light in the evenings to help your less curious fish to come out of the hiding spots as blue light mimics the moonlight.

Does blue light still cause algae?
Blue lighting can cause excess algae in freshwater and low Kelvin lighting, peaking in the red, can encourage algae in marine aquaria. Bulbs and tubes degrade over time, lowering their Kelvin rating, possibly causing more algae and producing light less useable by plants or corals.
